blender 27x keymap mis-match in 2.9- UV editor changing pivot point with value

Long time blender user here, love all the innovations since 2.8. But as a modeler power user, i have notice this bug/oversight, it hasn't been updated yet. In 2.79 image editor , the pivot point of UV transforming is map in the following way: . to set 2d cursor as pivot point , to use median point as pivot point this matches the hotkey for setting pivot point in 3d view.

but in 2.9, the uv editor, under "Blender 27X" keymapping, the same input calls the pie menu, it is so slow for me. I understand pie menu relieve beginners from remembering too many hotkey. But i am a power user using 2.79 key mapping, why punish me when i can remember all the hotkeys i need. why make me go thru the pie menu in 2d editor, but keep the behavior in 3d view editor? I think its a honest oversight by the devs, would appreciate if they to fix it soon.

i tried to set custom input to get the same mapping as 2.79. but no luck. the thing is the keymap not only has the context attribute but also a "value" in 2.79, but absent in 2.9. I have no idea how to add that to a new key-binding.

In the mean time if you know how to set it up properly as end users, please give me a shout. I really dont like using pie menu in my "blender 27x" key mapping. I don't mind you guys go nuts with pie menu in "2.9 key mapping', please leave our "blender 27x" keymapping as advertised.
